Oily Skin Guide: Causes, Treatment Types, and Oil-Control Solutions

Learn what causes oily skin and discover the most effective ingredients, cleansers, and skincare routines to control shine, minimize pores, and prevent breakouts.

What Causes Oily Skin?

Oily skin occurs when sebaceous glands produce excess sebum. While natural oil protects your skin, too much can clog pores and cause shine or breakouts.
  • Overactive oil glands
  • Hormonal changes
  • Genetics
  • Over-cleansing or stripping products
  • Hot or humid environments
Understanding what triggers oil production helps you control shine without damaging your skin barrier.
